Question

我正在用hibernate创建一个spring boot应用程序。但我无法访问其他包中的功能。这是由于不同的包裹吗？。

我的ManageController：

@Controller
public class ManageController {

    private ManageService manageService;

    @Autowired(required=true)
    //@Qualifier(value="manageService")
    public void setmanageService(ManageService ms){
        this.manageService = ms;
    }
@RequestMapping(value = "USER_LOGIN")
    public void user_login(Model model, HttpServletResponse response, HttpServletRequest request) throws JSONException, IOException  {
        try {
            StringBuilder username = new StringBuilder((String)request.getParameter("username"));
            StringBuilder password = new StringBuilder((String)request.getParameter("password"));
            List<JSONObject> json = new ArrayList<JSONObject>();
            System.out.println("1");
            System.out.println("username :"+username);
            System.out.println("password :"+password);

            Users users = this.manageService.getUsersByUsername (username.toString());
            System.out.println("2");


            if(users.getId() > 0) {
                JSONObject json_data = new JSONObject();
                if(users.getPassword().equals(password.toString())) {
                    json_data.put("status","true");
                    json_data.put("login","Success");
                }else {
                    json_data.put("status","false");
                    json_data.put("login","Incorrect password");
                }
                json.add(json_data);
            }

            response.getWriter().print("{\"result\":"+json+"}");

        }   catch   (Exception e){

            List<JSONObject> json1 = new ArrayList<JSONObject>();
            JSONObject json_data1 = new JSONObject();
            json_data1.put("status","false");
            json_data1.put("login","Incorrect username");
            json1.add(json_data1);

            response.getWriter().print("{\"result\":"+json1+"}");
        }
    }
}

此处无法访问该行：

Users users = this.manageService.getUsersByUsername （username.toString（））;

我的项目结构是：

在我的manageDao实现中，我正在调用无法访问的函数;

@Repository
public class ManageDaoImpl implements ManageDao {

    private static final Logger logger = LoggerFactory.getLogger(ManageDaoImpl.class);

    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sf){
        this.sessionFactory = sf;
    }

@Override
    public Users getUsersByUsername (String username) {
        System.out.println("11");
        System.out.println("11 username:"+username);
        Session session = this.sessionFactory.getCurrentSession();
        System.out.println("12");

        Criteria cr = session.createCriteria(Users.class);
        System.out.println("13");

        cr.add(Restrictions.eq("username", username));
        System.out.println("14");

        cr.add(Restrictions.eq("active", 1));
        System.out.println("15");

        Users ul = (Users) cr.uniqueResult();
        System.out.println("16");

        return ul;
    }
}

最后主要的课程是：

@SpringBootApplication
@EnableAutoConfiguration
//@ComponentScan(basePackages = { "com.paymark"})
@ComponentScan(basePackages = { "com.paymark.app","com.paymark.views","com.paymark.app.dao","com.paymark.app.model","com.paymark.app.service"})
public class PaymarkApplication {

    public static void main(String[] args) {
        SpringApplication.run(PaymarkApplication.class, args);
    }
}

是否与配置问题有关？无法访问任何功能？最初，错误与bean有关。像：

考虑定义类型的bean 您的配置中的“com.paymark.app.service.ManageService”。

所以我删除了：

@Qualifier（值= “manageService”）来自管理服务。但现在错误仍然没有，任何功能都无法访问..

更新：在ManageService中：

public interface ManageService {
    public Users getUsersByUsername (String username);

}

在ManageServiceImplementation中：

@Service
public class ManageServiceImpl implements ManageService {

    private ManageDao manageDAO;
    @Override
        @Transactional
        public Users getUsersByUsername (String username) {
            return this.manageDAO.getUsersByUsername(username);
        }
}
